Thank you very much for viewing. These are NIKE RZN TOUR PLATINUM golf balls that I previously purchased from the Nike official website. This is a very rare dozen set of balls with a different logo on each sleeve, and all the numbers are 1. They feel great when hit and are a good item for both rounds and collections. I took them out of the box for the photos, but they are new and unused, and have been stored in a dark place. - Brand: Nike - Model Name: RZN TOUR - Ball Design: Bunker, Accuracy, Pin Flag, Aim - Core Technology: Speedlock X Core - Cover Material: Flight Suit Cover - Mantle Technology: Speedlock Mantle
